Pronunciation of February

Feb·ru·ary - Although the variant pronunciation (fby-r) is often censured because it doesn't reflect the spelling of the word, it is quite common in educated speech and is generally considered acceptable. The loss of the first r in this pronunciation can be accounted for by the phonological process known as dissimilation, by which similar sounds in a word tend to become less similar. In the case of February, the loss of the first r is also owing to the influence of January, which has only one r.
